What type of electro magnetic waves could make it thru the holes in the foil? And what sort could make it thru the hole at end of the box?

THANK YOU!

Weird question is a server rack, two solid walls on both side with grates on the back and front with holes smaller then the ones he showed here work as one and if it would does would it still work if what ever is connected inside is connected to wires outside

Is their a relationship in the size of the EMP and the needed size of a cage? Basically can a small cage be overwhelmed?

P.S. I add double the layer too.

Now tell us about why the radio reception increases as soon as your fingers come in contact with the radio. As kids we were fascinated by TV antenna.

Aluminum foil is a conductive material, as most metals are, and increase the surface area of the antenna by absorbing the electromagnetic signal (radio waves) and conducting it through the foil into the tv antenna. Think of the antenna like a target, and the radio wave like a bullet coming out of a gun. It’s hard to hit a small target, so adding aluminum foil to make the target bigger makes it easier to hit. Hope this answers your question.

What happens if there are no holes whatsoever on the foil around the box? Does that make it a stronger Faraday Cage? Also, an EMP has an extremely powerful E1, E2, and E3. Does the foil protect it in that case?

Smaller holes blocks even higher frequencies. With no holes not even light comes in.

Based on your drawing it seems like it would be AMPLITUDE limited by the hole diameter, not wavelength. The time dimension defining wavelength is not a dimension at play in the "hole" in the foil.

I fix appliances. Same concept with microwave doors with the slotted small holes that block microwaves so that you can see inside safely

I’m researching on how to keep a inverter generator and solar panels safe from EMP/solar flares, tin-foiling the box they both came in and sealing them with metal tape may be the solution.

Faraday cages are only effective in blocking radio waves within the confines of the cage. If you are interested in disrupting radio or cellphone signals within a designated area, you would need to procure a “jamming device”, which is a device that emits powerful radio waves with the intention of overriding weaker radio waves. In this example, think of a radio wave like a small speaker playing music, and the jammer as a large speaker. When the large speaker is off, you can hear the small speaker, but if you turn on the large speaker, the small speaker is still making noise, but you can no longer understand what is coming out of it. Additionally, please be aware that certain uses of jamming devices are illegal in different states and countries, and it is within your best interest to do research on your local laws regarding jamming devices, where to procure a jamming device, and how to optimally operate one. Hope this answered your question.

Even if you do make a Faraday cage that protects your devices, you are still missing one key essential item that you will never get to make them truly worth investing time and money into. Preppers can't think far enough outside the box to realize what it is they are missing.

Hello 👋🏻 why do people say to put devices in a faraday cage now before an emp happens? They say it’ll protect your device and it’ll be usable? But we saw what happened when AT&T and some other networks went down. They’d be almost useless without wifi. Can you explain

So theoretically, it would be possible to create a Faraday cage in which we couldn't see the objects inside?

Should it be grounded or not?

No actually, they are not small paraday's cages.

Radar could easily lock on and shot down small target aircraft if they cannot proper communicate with it, but no way in hell they would do the same with fishing boats, since wouldnt have proper communication)

In essence the metal acts like a mirror for the electromagnetic wave the reflection is out of phase and cancels the incoming wave. Its more complicated than this because there is reflection, absorption, and attenuation, as the wave passes through. The most important factor is the penetration depth of the material depending on the properties of the material and the incoming wavelength. Longer wavelengths can penetrate more deeply into materials (including metals) than can shorter wavelengths. Light can't penetrate dry wall but WiFi can

No, they are not necessary. He only demonstrates that you can also have holes in the box, as long as they are smaller than the wavelength. For example, microwave ovens also have holes that allow short-waved light (400-700 nanometers) to pass throw them, while also blocking the long-waved (~12 cm long) microwaves radiation. Another example is the elevator, where your phone signals can get blocked without having holes in the elevator. So no, it's not necessary.

A faraday cage blocks minute electromagnetic radiation, typically in the form of a radio wave. The intention behind the faraday cage is not to shield against electromagnetic pulses. Most EMP weapons are not designed to target specific households or private properties, but instead disrupt electricity production or distribution by targeting generation sites and distribution centers. Additionally, the majority of war or terrorism related electricity disruptions occur from physical munitions or explosives which directly destroy the site of electricity generation or distribution, exacerbating the period in which electricity is unavailable.
